If the Shape Fits

This If the Shape Fits lesson plan also includes:

Geometers juggle the idea of polygons. Using a game and manipulatives, they make trapezoids and irregular polygons. They review the algorithms for finding the areas of squares and rectangles. On day one, they find the area of trapezoids, and on day two they find the area of irregular polygons. This lesson plan has links to the game cards, projection images, assessments, and other handouts.
